Ready to Start Backing Up Your PostgreSQL Database
Wondering how to back up a PostgreSQL database? If so, then you've come to the right place. Ibitz Backup Database Solutions will explain how to back up your PostgreSQL database in simple, easy-to-understand steps. But first, what exactly is PostgreSQL?
What is PostgreSQL?
PostgreSQL is a newer, more modern database management system, and it's becoming more popular by the day. Many developers are using it as a reliable database management system and primary location for storing databases.
Of course, just as with any other sort of valuable data, it is vital to have a strategic backup plan to protect yourself from data loss. Without further ado, here are the steps how to backup PostgreSQL databases.
How to back up a PostgreSQL Database Using a pg_dump
PostgreSQL comes equipped with fantastic functionality, such as a handy backup instrument called a "pg_dump." The pg_dump service allows users to dump their entire database contents for quick and easy backup and location. The pg_dump tool can be used conveniently from the Linux command line.
Of course, you need to make sure that whoever is initiating this command has privileged access to the database and all database contents in question.
If you find yourself needing to back up a remote system, the process is also pretty straightforward. Simply use the "-h" flag to identify the remote host, and then use the "-p" flag to identify the remote port.
The PostgreSQL system will be prompt for authentication each time you use a pg_dump, just as it does with the other client programs. Be sure beforehand that your login credentials are current and valid for the systems you need to be backed up, or you will not be able to access your data.
How to Restore Data Dumps from pg_dump with PostgreSQL
If you need to restore or recreate a backup that you created in pg_dump, you can do so by just redirecting the file into SQL. You will also need to grant specific permissions for any users to access contents within the database. To use a real-world example, if your database has a table owned by "main_user," it must first be created in the restoration system.
